3GPP doesn’t build networks.
But it builds the blueprint for the networks.
3GPP isn’t one group.
Here are 3 of those:
-
TSG RAN:
→ Defines the radio interface.
→ It covers layers, interfaces, and performance. -
TSG CT
→ Handles core protocols.
→ It ensures interworking and policy control. -
TSG SA:
→ Sets the framework.
→ It governs architecture, security, and services.
Each has multiple working groups.
But why should you care?
Because standards drive innovation.
Every major advancement starts here.
NR
RedCap
NTN
TSN
None exist without 3GPP.
So, how to track it all?
Follow updates.
Every release refines the ecosystem.
Track dependencies.
Each spec links to another.
Think beyond compliance.
The real impact is in optimizations.
The Telco industry moves fast.
Standards move faster.
Best time to learn about 3GPP was yesterday.
Second best?
Now.
